How to reinvent relationship with Aquarius

So, after separation in marriage with Aquarius and sorting out why it happened (I pushed him literally into the arms of another women due to emotional abuse and never wanting to go socialize with him anywhere or leave house bc after having baby I gained wait and became depressed and took it out on him and was no longer worried about his needs or feelings, when he told me he is not getting from me what he needs i totally disregarded his needs in relatinship for selfish reasons) Anyways, it wasn't cheating since we were broken up and I portrayed that I was going out and meeting other people)

Anyways lol we have sorted out the reasons we broke up and have decided to try it again. We are living apart still and have children and only see eachother once a week. I know he likes space but it seems as if he never has time for me (bc he says i always bring up the other girl, which i have stopped) So now that i've stopped how do I start to gain his interest again. He will stay with me in marriage because he wants our family together and will continue our marriage unhappily bc he doesnt want to hurt the children (which he would never admit to me or even himself), and I dont want that. I want to gain his interest again from genuine connections and I'm not sure how to do it with an aquarius. When we spend time together our intellectual stimulation is always amazing. (when i dont bring up past, which i will stop) so its like, I just have to get him to start giving me the time. How do I do this? It's like even if we take steps forward, that connection we start rebuilding gets "deleted" bc of the lack of time we spend together. The first year and half we were together at all times, did everything together, and wanted to. It's like since im not living with him it's "out of sight out of mind" and this is how he started a new relationship in the past. I know there isnt someone else CURRENTLY, but i feel like its just a set up for him to start another relationship with someone at his new job or his new circle of friends. He literally says he loves spending time with me and talking to me and is one of the main reasons he holds on to our marriage bc he has never had that with anyone else but he holds back spending more time with me bc hes afraid i will always talk about past and that makes him resent me. Is this separation going to give him too much space to completely fall out of love with me? Is it better to just seperate until we live together? I don't want to TRAP him into thinking he HAS to be with me for kids. I want the genuine thing we use to have. It seems like the circumstances of our living situation and the initial separation and the experience of being with someone else and the excitement of that new relationship is deep down making him not interested in our marriage anymore. How do I show him I'm still that person from the beginning (I was suffering from post partum depression when these issues started and am stable again mentally and have lost all my weight which is a huge thing for my self esteem which is important in being my whole hearted mentally happy positive self)

Sorry for misspellings i rushed to type this
